Rapid Absolute Neutrophil Count Testing Guides Targeted Antimicrobial Therapy in Febrile Pediatric Oncology Patients.

OBJECTIVES: It is well established that early antibiotic administration leads to improved outcomes in febrile neutropenic patients. To achieve this, many institutions administer empiric antibiotics to all febrile oncology patients in the emergency setting, before knowing their neutropenic status. This study evaluates the role of rapid absolute neutrophil count (ANC) testing in the targeted antimicrobial management of nonneutropenic febrile oncology patients. METHODS: We conducted a retrospective review of patients 19 years or younger presenting to the pediatric emergency service with an oncologic process and fever or history of fever. We examined the administration of antibiotics and outcomes in nonneutropenic patients. RESULTS: We included 101 patient encounters, representing 62 distinct patients. The rapid ANC test influenced antibiotic management in 94% (95/101) of patient encounters and resulted in no antibiotics or targeted antibiotic therapy in 88% (60/68) of nonneutropenic patients. Use of the rapid ANC test to guide treatment would have spared antibiotic administration in 68% (46/68) of well-appearing nonneutropenic patients with no alternate indication. No well-appearing, nonneutropenic patient had a positive blood culture, and only 1 required hospital admission on a repeat visit. CONCLUSIONS: The rapid ANC is a useful tool to balance the goal of early antibiotic administration in febrile neutropenic oncology patients while promoting antibiotic stewardship in this vulnerable population.

Automated identification and quality measurement for pediatric convulsive status epilepticus.

OBJECTIVE: Treatment delays for refractory convulsive status epilepticus (RCSE) are associated with worse outcomes. In the United States, treatment for pediatric RCSE is slower than guidelines recommend. To address this gap, the American Academy of Neurology and Child Neurology Society (AAN/CNS) developed a quality measure: the percentage of RCSE patients that receive third-line treatment within 60 minutes. We aimed to develop computable phenotypes for convulsive status epilepticus (CSE) and RCSE to automate calculation of the quality measure. METHODS: From an observational cohort of children presenting to the emergency department for seizures or epilepsy, we identified presentations of RCSE and its precursors: CSE and benzodiazepine-resistant status epilepticus (BRSE). These served as a gold standard for computable phenotype development. Using multivariate analyses, we constructed and evaluated statistical models for case identification. We then evaluated adherence to the AAN/CNS RCSE quality measure. RESULTS: From 664 charts, we identified 56 patients with CSE, 36 with BRSE, and 18 with RCSE. Four predictors were used: International Classification of Diseases (ICD) codes, and receiving first-, second-, or third-line agents shortly after presentation to the emergency department (ED). Combinations of these predictors identified CSE with 84% sensitivity and 81% positive predictive value (PPV), BRSE with 67% sensitivity and 89% PPV, and RCSE with 94% sensitivity and 85% PPV. Median (interquartile range [IQR]) time to treatment for first-line agent was 13 (5-27) minutes for CSE, second-line for BRSE was 24 (9.5-43.5) minutes, and third-line for RCSE was 52 (27-87) minutes. Sixty percent of RCSE patients received a third-line agent within 60 minutes of ED arrival. SIGNIFICANCE: RCSE and its precursors can be identified automatically with high fidelity allowing automated calculation of time to treatment and the RCSE quality measure. This has the potential to facilitate quality improvement work and improve care for RCSE.

Impact of a Child Life and Music Therapy Procedural Support Intervention on Parental Perception of Their Child's Distress During Intravenous Placement.

OBJECTIVES: Child life specialists and music therapists have a unique and integral role in providing psychosocial care to pediatric patients and families. These professionals are trained to provide clinical interventions that support coping and adjustment and reduce the risk of psychological trauma related to hospital visits and health care encounters. The researchers devised a multimodal approach using a combined child life and music therapy intervention to address procedure-related distress in patients receiving intravenous (IV) placement in the pediatric emergency department. The aim of this study was to investigate the efficacy of this collaborative intervention by evaluating parental perception of their child's distress. METHODS: This study was a prospective analysis investigating the impact of a child life and music therapy intervention on children aged 4 to 11 years old receiving an IV placement in the pediatric emergency department. Efficacy was evaluated by comparing scores between a 4-question pretest and subsequent 4-question posttest that asked the child's parent to evaluate how they anticipated their child would respond to the procedure, and then to evaluate how they perceived their child to have responded after the procedure. Qualitative data were collected in the form of open-ended comments, which were accommodated at the end of the posttest. Data were analyzed by the Cochran-Mantel-Haenszel method for testing repeated ordinal responses and the PROC GENMOD procedure in the SAS system software. RESULTS: A total of 41 participants were enrolled in this study. Results of the statistical analysis revealed significant differences between all pre- and posttest scores (P < 0.05), and significant likelihood that the patient would improve relative to the 4 questions, as a result of the child life and music therapy intervention. CONCLUSIONS: Improvement was demonstrated across all 4 questions, suggesting that the child life and music therapy intervention supported healthy, adaptive coping and helped to minimize distress experienced by patients during IV placement. These results underscore the importance and potential clinical impact of child life psychological preparation and psychotherapy-based music therapy interventions in reducing distress in pediatric patients during common medical procedures.

Predictors of fluid resuscitation in pediatric trauma patients.

Advanced Trauma Life Support (ATLS) is accepted as the standard for the first hours of trauma care. However, ATLS is designed primarily for adults. In children, vascular access can be difficult and time-consuming. Due to the differences in the epidemiology of children suffering traumatic injury, they may not require aggressive fluid resuscitation. The objective of the study was to establish predictors of fluid resuscitation, and to determine whether all pediatric Level I Trauma victims require two intravenous catheters. Medical charts of all patients aged < 18 years meeting Level I Trauma criteria who presented to Childrens Hospital Los Angeles (CHLA) between January 1 and December 31, 1999 were retrospectively reviewed. There were 152 patients reviewed with a median age of 6 years (range 4 months to 17 years); 64% were boys. The mechanism of injury was motor vehicle crash 49%, fall 37%, crush 8%, gunshot 5%, and knife 1%. Injuries included closed head 88%, penetrating abdomen/chest 6%, and other 6%. Vital signs over time showed no change in 59%, got better in 34%, and got worse in 7%. Fluid resuscitation included no bolus in 70%, 1 bolus in 20%, 2 boluses in 7%, > 2 boluses in 3%. The ICU admitted 23%, 12% were intubated, survival was 95%, and 59% received a prehospital i.v. The i.v. #1 site: antecubital 51%, hand 41%, foot 5%, femoral 1%. The i.v. #2 site: hand 30%, antecubital 20%, foot 2%, none 48%. T test showed no statistically significant differences in fluid resuscitation or second i.v. placement based on the mechanism of injury. T test for unequal variances showed a statistically significant difference in means with p < 0.001 for second i.v. placement as compared with only i.v. fluid amount, age, and Injury Severity Score (ISS). Revised Trauma Score was the only predictor of worsening of vital signs (logistic regression [LR], p < 0.001). Age was the only predictor of second i.v. placement (LR, p < 0.03). ISS was the only predictor of a bolus being given (LR, p < 0.01). In our study, blunt trauma occurred in 90% of children, with 10% requiring > 1 fluid bolus. ISS was the only predictor of the need for fluid resuscitation and is not likely to be helpful in the clinical setting. In our population, nearly 50% had no second i.v. This preliminary review of the nature of pediatric trauma suggests that ATLS guidelines may not always be appropriate for the management of pediatric trauma.
